Why is rustup 1.26 the newest available version of rustup?

Help

due to some unfortunate circumstances I have been forced to use google’s IDX IDE for my rust projects, but I was shocked that there’s no way for me to install a current version of rustup to actually use current packages.

1.26 was released in early 2023, why is that the newest version of rustup available on the current stable build? Surely there’s a good reason.

PR with 1.27.1 was merged into master a few days ago:

So it’s just a matter of waiting until it gets to unstable.
Otherwise, rustup may not be the best way to do things with nix (not sure it even works properly ootb).

This.

Here’s an example Rust project with Nix.

I’m having some trouble understanding how the example project ties into solving the issue with rustup not working properly with Nix.

Could you clarify what steps or changes are recommended for setting up rustup correctly in this context? Or, if rustup isn’t the best option, what alternative workflow would you suggest for managing Rust versions in a Nix-based environment? I’m relatively new to using Nix with Rust, so any additional details would be super helpful!

Rustup is incompatible with the idea behind Nix. I have been using nix-cargo-integration successfully. So that’s nice.

Thank you that is useful. Are there any other recommendation in for newer adopters who are using home-manager?

Well, if you mention home-manager, then yes, I do have another tidbit for you. That it should have nothing to do with home-manager. home-manager is for building a general purpose working environment for you. A user’s home. But a typical Nix user wants their projects to be self-contained. That is, they’d include all of the dependencies needed to build the project. And perhaps some other tooling.
